Mastering Lightning from Hogwarts

When it came time to test the Rune of Barren Thunder, Anduin first took out a crystal ball that could temporarily bear magic runes, and then used magic to construct a complete magic rune, pouring it into the crystal ball. Read more

Afterwards, Anduin didn't immediately start using the discharger to electrify the magic rune, but instead raised his left hand towards the crystal ball.

At this moment, a silver snake slowly extended from Anduin's sleeve, it was his spirit-bound snake. The spirit-bound snake stretched its head in front of the crystal ball, then slowly opened its mouth and sucked in with all its might.

Subsequently, the Rune of Barren Thunder in the crystal ball visibly dimmed. Of course, Anduin didn't draw all the magic power from it, but left a portion within the magic rune.

He did this because of the special nature of the Rune of Barren Thunder.

A complete Rune of Barren Thunder can actually store a large amount of lightning-attributed magic power, and can even be said to compress almost infinite electrical energy into it, just like his 'God-Slaying Strike', which compresses a large amount of magic power into the magic rune, converting it into shockingly damaging lightning.

However, the higher the lightning density in the Rune of Barren Thunder, the more difficult it is to charge it. Anduin felt that if he directly used the complete Rune of Barren Thunder, even a generator might not be able to force the generated current into the magic rune.→

So, first extract a portion of the magic power from the magic rune, so that it can be better observed.

Afterwards, Anduin held the generator and began to discharge electricity towards the Rune of Barren Thunder.

Sure enough, as Anduin expected, natural electricity could indeed react with the Rune of Barren Thunder.

The crackling current between the two prongs of the generator approached the magic rune, and then, as if attracted by something, slowly but continuously flowed into the magic rune.

The originally dim Rune of Barren Thunder also began to slowly brighten as electricity flowed in, until after continuously inputting for dozens of seconds, the light on the Rune of Barren Thunder became even more dazzling than when it was first summoned.

But at this time, the current in the generator stopped flowing into the magic rune, obviously the electrical energy density within the magic rune had become relatively saturated, and the generator's pressure was no longer sufficient to continue discharging electricity into it.

Afterwards, Anduin tested an ordinary lightning magic rune again, wanting to see if only the Rune of Barren Thunder was so special, but the result told him that only the Rune of Barren Thunder was so special, ordinary lightning magic runes had no reaction to natural electrical energy at all.

However, Anduin was already very satisfied with this. This test had proven that the Rune of Barren Thunder could indeed absorb natural lightning.

If that's the case, then his previous idea could be realized. As long as electrical energy is replenished into the Rune of Barren Thunder, and then magic power is extracted from the Rune of Barren Thunder, it would be equivalent to completing the conversion from electrical energy to magic power.

Although such steps are indeed more troublesome, and it seems that only Anduin, who holds the Rune of Barren Thunder, can do this.

However, with such a troublesome conversion method, the loss must be significant, and the next thing to do is to test a plan with the smallest loss and the highest conversion efficiency.

Subsequently, in the remaining month of the summer vacation, Anduin completely holed himself up in the basement, wholeheartedly doing experiments on converters.

What kind of material should be used for the converter, what kind of structure should be used for the magic rune, whether it should be engraved on the material or directly stored in the energy storage crystal, and the impact of the size and specifications of the instrument on the conversion efficiency, etc., all need to be tested one by one.

Anduin didn't have any clever methods for this, he could only use the brute-force method, testing each material and each method.

As a result, he kept working until the entire summer vacation was about to end, and he still couldn't find the most satisfactory converter plan, let alone the lathe that was still on the drawing board.

It seems that it is impossible to complete the design and manufacturing of the lathe during this summer vacation. I can only transfer this part of the work to Hogwarts to continue.

Anduin pondered the progress in his mind, knowing that it couldn't be completed in a short time, so he decisively suspended the experiment.

There is still a week before the start of school, and he plans to use this week to visit his long-lost friends, such as the Longbottom family and the Weasley family.

Since Anduin returned to his home in Diagon Alley, he had hardly gone out, staying in the laboratory all day doing research, which was even more outrageous than at Hogwarts.

So, he also planned to take this opportunity to relax.

Anduin spent half a day specifically going out to buy some magical toys. The alchemical tools he made himself were too dangerous and not suitable as gifts.

He bought toy brooms for the younger children like Neville, Ron, and Ginny, and bought a whole set of Quidditch equipment for the other older children, as well as some goggles and other equipment. He knew that the Weasley children were very obsessed with Quidditch.

Afterwards, he asked Qi Qi to watch the house, and spent a few days taking Huo Ge to visit the Longbottom and Weasley families. He didn't dare leave this husky directly at home unattended, he had to keep it with him at all times.

The Longbottom family hadn't changed much, except that little Neville had grown a bit taller. It was obvious that Augusta took good care of Neville, and his nutritional intake was very rich. Little Neville's physique could be described as robust now.

What made Anduin relatively gratified was that Neville still remembered him after almost a year. It was actually quite good for a younger child to have this memory.

However, Augusta was still very strict with Neville. Perhaps it was because she had high expectations, even though Neville was only 5 years old, he already seemed extremely well-behaved under her strict guidance.

Anduin had a good dinner with the old and the young, and played with Neville for a while, before returning to Diagon Alley in the other's reluctant gaze.

Visiting the Weasley family was more lively, or rather, their home had always been more lively.

This year, the Weasleys had a very important event, that was their second son, Charlie, was about to enter Hogwarts.

When Anduin arrived at the Burrow, the Weasley children were playfully dressing Charlie in his newly bought school uniform.

They originally wanted to give Charlie Bill's discarded first-year school uniform to wear, but Bill's old clothes were too tattered.

During the period when Bill first started training under Anduin, he basically wore his school uniform to participate in training, and as a result, a year's worth of wear and tear had almost ruined it.

Later, Anduin bought them all a uniform set of sportswear, which solved the problem of running in robes.

And upon seeing Anduin's arrival, the Weasley children were even more excited, and they hurriedly surrounded him to greet Anduin, the big brother who had conquered them with delicious food.
